Ivhu ndicho chinhu chakakosha pakurima maruva, kudya kwemidzi yemaruva, uye tsime rekudya, mvura nemhepo.Midzi yemiti inotora kudya kubva muvhu kuti idye uye ibudirire pachayo.
Ivhu rinoumbwa nemamineral, organic matter, mvura nemhepo.Maminerari ari muvhu ane granular uye anogona kupatsanurwa kuita ivhu rejecha, ivhu uye loam zvichienderana nekukura kwechikamu.
Ijecha rinodarika 80% uye ivhu rinotora isingasviki 20%.Jecha rine zvakanakira pores hombe uye yakatsetseka drainage.Izvo zvisingabatsiri kusachengeteka kwemvura uye nyore kuomesa.Naizvozvo, jecha ndicho chinhu chikuru chekugadzirira ivhu retsika.Yakanaka mhepo permeability, inoshandiswa sekucheka matrix, nyore kutora midzi.Nekuda kwekuderera kwefetereza muvhu rejecha, manyowa akawandisa anofanira kuiswa pamaruva akasimwa muvhu iri kuti avandudze zvinhu zvevhu rejecha.Ivhu rejecha rine kunyura kwakasimba kwechiedza nekupisa, tembiricha yepamusoro yevhu, kukura kwakasimba kwemaruva uye kutanga maruva.Jecha rinogonawo kuiswa pasi pebheseni sechitubu chemvura.
Ivhu rinoita zvinopfuura 60% uye jecha risingasviki 40%.Ivhu rakanaka uye rinonamira, uye ivhu rinotsemuka kuita matombo panguva yekusanaya kwemvura.Izvo zvinonetsa mukurima uye manejimendi, zviri nyore kuomesa uye kutadza kwemvura.Sunungura ivhu uye udonhe mvura yemvura nenguva.Kana akabatwa zvakanaka, maruva anogona kukura zvakanaka uye maruva akawanda.Nemhaka yokuti ivhu rine fetireza yakanaka uye inochengeta mvura, rinogona kudzivirira kurasikirwa nemvura nefetireza.Maruva anokura zvishoma nezvishoma muvhu iri uye zvirimwa zvipfupi uye zvakasimba.Paunenge uchidyara maruva muvhu rinorema, zvakakosha kusanganisa yakawanda yakaora mashizha ivhu, humus ivhu kana ivhu rejecha kuti uvandudze zvinhu.Kushandura ivhu uye kudiridza kwechando kuchaitwa munguva yechando kusunungura ivhu uye kufambisa kurima.
Loam ivhu riri pakati pevhu rejecha nevhu, uye zviri mujecha nevhu zvinotora hafu zvakateerana.Avo vane jecha rakawanda vanonzi sandy loam kana light loam.Avo vane ivhu rakawanda vanonzi clayey loam kana weighing loam.
Pamusoro pemhando nhatu dziri pamusoro pevhu remaruva, kuti uwane chimwe chinangwa, mamwe marudzi akati wandei evhu anogona kugadzirwa, senge humus ivhu, peat ivhu, yakaora mashizha ivhu, yakaora huswa ivhu, ivhu rematanda, gomo dope, ivhu reasidhi, nezvimwewo.
